Setting Up Programming Languages

Setting up programming languages can take some time and differs per language. Here are some guides on each one to get you up and running in no time. NOTE: This guide is intended for macOS development.

M1 Macs & Homebrew: You will need to add the following to your path: /opt/homebrew/bin and /opt/homebrew/sbin

CSharp

Run brew install --cask dotnet-sdk to get started. This will install the SDK along with Mono. See the C# page for more information: https://formulae.brew.sh/cask/dotnet-sdk

import os

# Invert a dictionary's keys and values

FILE = os.getenv('FILE')

Multisite Docker Server via Traefik

Quickly setup multiple websites via Docker containers on a single server via Traefik.

Edit the email found in the traefik.toml file and run docker compose up -d to get started in production (LetsEncrypt will generate SSL certs for all your sites).

If you'd like to use Traefik during development, you'll want to comment out the lines that have SSL/HTTPS/443 comments/code in the docker-compose.yml file.

Hosts: You'll need to add each site url to your /etc/hosts file before it can be visited.

Resetting MySQL Replication

If you have a master/slave replication setup that comes across something similar to error 1236 where the binlogs get out of sync, you can run the following commands to get things back on track.

# On the master node
SHOW MASTER STATUS;

# On the slave node
STOP SLAVE;

Package non-Python Assets into your Python Package

There are times where you may need to include non-Python assets in your Python package for distribution. This may include data files or JSON assets from a submodule for example that your Python package needs to reference. By default, Python will not include these assets in the bdist/sdist. You can either include an empty __init__.py file in that submodule (even if the project isn't Python) and rely on the magic of packages=setuptools.find_packages() in setup.py or you can explicitly include those non-Python assets by using the following steps.

1. In setup.py, include an array of locations to include. These are glob matching patterns. An example of this looks like the following:

package_data={
    'top_level_package': [
 'path/to/assets/one/*.json',

import requests

# Gets the complete list of AWS IP ranges and parses the results
# Usage: venv/bin/python aws_ip_range_parser.py

AWS_IP_URL = 'https://ip-ranges.amazonaws.com/ip-ranges.json'
REGIONS_TO_FILTER = [
    'us-east-2',
    'us-west-2',
]
